Description

A kind of insulation bird thorn

One, technical field

The utility model relates to a kind of insulation bird thorn.

Two, background technology

In recent years, because the numerous countries in the China and the world strengthen environmental protection and ecological protection, various birds populations are able to a large amount of procreations.Therefore, birds happen occasionally to the pollution flashover power failure phenomenon that line security brings.Particularly in the river, the wetland migratory bird migrates the circuit of process, become the spot of major accident.

In order to prevent the generation of bird pest accident, adopt steel strand wires welding bird to sting or protect in the past to increasing large-scale full skirt on the insulator, it has following shortcoming:

1, security reliability is low.The existing steel strand wires type bird thorn that uses is conductive material, and bird thorn in the installation and removal process or in the day-to-day operation in case come off falls down, and the bird thorn is during near lead or insulator chain, will short circuit dischange, and accidents caused, security reliability is low.

2, pretective acreage is little.The steel wire of general steel strand wires type bird thorn is all done shortlyer, thereby the area of its protection is just little, to such an extent as to the circuit that steel strand wires type bird thorn has been installed has the bird pest accident to take place also the time.

3, steel strand wires solder side and steel wire easily get rusty.After steel strand wires solder side and steel wire got rusty, iron rust can be dropped on the insulator chain, can influence the insulator chain performance, also increased the cleaning difficulty of porcelain vase simultaneously.

4, dismounting inconvenient maintenance.Existing bird thorn fixing means is too simply backward, is not easy to dismounting, also can guard against the people when preventing bird, brings difficulty, dismounting inconvenient maintenance by the cross-arm maintenance for the repairing workman.

Three, utility model content

The utility model has solved that bird thorn security reliability in the background technology is low, pretective acreage is little and the technical problem of dismounting inconvenient maintenance.

Technical solution of the present utility model is: the utility model comprises main body 2, and its special character is: described main body 2 is provided with insulation thorn 1, and main body 2 bottoms are provided with base 6.

Aforementioned body 2 is hemisphere or arc surface cuboid.

Above-mentioned insulation thorn 1 adopts welding or movable the connection with 2 of main bodys.

6 employing activities of aforementioned body 2 and base connect.

Aforementioned body 2 bottoms are provided with dead lever 3, and base 6 comprises and has the insertion sleeve pipe 4 and the holder 8 that can insert dead lever 3, inserts sleeve pipe 4 and is arranged on the holder 8.

Above-mentioned insertion sleeve pipe 4 sidewalls are provided with spring pin 5.

Said fixing bar 3 is a circular pin, and the endoporus that inserts in the sleeve pipe 4 corresponds to circle.

Said fixing seat 8 is a U type base, and the bottom is provided with holding screw 7.

Said fixing bar 3 is a square pole, and the endoporus that inserts sleeve pipe 4 corresponds to square.

Said fixing seat 8 comprises connecting plate 9 and locking bail 10, inserts sleeve pipe 4 and is arranged on the connecting plate 9, and both sides, connecting plate 9 below are provided with locking bail 10.

The utlity model has following advantage:

1, security reliability height.The utility model is to adopt alkali-free glass fibre and the manufacturing of epoxy resin synthetic material, and it has advantages such as good insulating properties, mechanical strength height and antiultraviolet are aging, also can not cause the porcelain vase short circuit even it is placed on the insulator chain.

2, protective range is big.Because insulation thorn of the present utility model is high dielectric material, does not have short circuit to threaten, the insulation thorn just can extend according to actual needs, thereby has enlarged protective range, and the distance that birds need be avoided increases greatly, and the safety of circuit is able to further raising.

3, the utility model adopts alkali-free glass fibre and epoxy resin synthetic material to make, and is not afraid of wind and weather, non-corrosive, can increase pollution flashover.

4, dismounting is easy to maintenance.Main body of the present utility model and base adopt split-type structural, install and fix base and to pull down main body all very convenient, can extract easily or insert when the workman overhauls, and dismounting is easy to maintenance.
